Symptoms
When an InstallShield Developer setup is launched, the following error occurs:
"Error -1608: Unable to create InstallDriver instance"
--------------------------------------------------------------------------------
Cause
Little information is known at this time about the specific cause of this initialization error since it rarely occurs and is typically encountered on an intermittent or machine-specific basis. Some known causes for this error are as follows:
Windows 98 machines do not have Microsoft DCOM98 installed properly
DCOM permissions are not set to an adequate level
The InstallScript engine was not installed properly
The operating system has become corrupted
Other applications or utilities are running in the background and causing a conflict
Insufficient privileges in Windows
--------------------------------------------------------------------------------
Resolution
The following options have been known to resolve this error message in the majority of cases:
Reinstall the InstallScript engine by running the "msicu.exe" file located in the following location:
http://support.microsoft.com/default...;en-us;q238413 This file will try to cleanup all any problems with the Windows Installer.
Reset the DCOM permissions by following the steps below:
Launch the utility DCOMConfig by typing "dcomcnfg" in the Windows Run dialog.
Select the Default Security tab.
Click the Edit Default button in the Default Access Permissions section.
Make sure you choose Allow Access permissions.
Click OK in the utility, and re-run the InstallShield Developer setup.
Empty all temporary folders. The specific temporary folders for a machine can be determined by accessing the DOS prompt and typing "set". Note the values listed for "TEMP" and "TMP", and delete all files in those locations.
Make sure no other applications, including utilities such as virus scanners, are running in the background. Close all running applications and utilities, and launch the InstallShield Developer setup again.
If this occurs on a Windows 98 machine, install Microsoft DCOM98 from the link below, and re-run the InstallShield Developer setup:

Make sure you have full administrative rights for that particular system.
Reinstall the Operating System, as this behavior has been known to occur when an environment has been corrupted.
